Filed: 1991-07-30
Abstract: THROMBECTOMY METHOD AND DEVICE                ABSTRACT OF THE DISCLOSURE      A method of and apparatus for removing a thrombus deposit from the cardiovascular system of a patient without the need to surgically access the location of the thrombus deposit via a cut-down or other surgical procedure. A catheter is inserted percutaneously into the patient at a convenient location either directly or over a previously positioned guide wire.   The distal end of the catheter is advanced under fluoroscopy to the  site  of  the  thrombus  deposit.    A  balloon  is inflated to stabilize the position of the distal end of the catheter within the center of the vessel lumen.  A flexible metal tube conveys an extremely high pressure stream of sterile saline solution to at least one jet at the distal end of the catheter.   At least one jet positions the thrombus deposit for emulsification by at least one other jet.  By directing the jets toward the orifice of the large evacuation lumen of the catheter, a  stagnation pressure  is  induced which propels  the emulsion proximally for disposal.  The rate of proximal flow of  effluent is metered to correspond with the distal flow of saline solution to ensure minimal local impact on the vasculature at the site of the thrombus deposit.

Title: Lcd addressing system
Inventor: SCHEFFER TERRY J
IPC: G02F1/133
Filed: 1992-02-06
Abstract: A method and apparatus for addressing faster responding liquid crystal panels (LCDs) so that video rate, high information content LCDs having time constants on the order of 50ms or less, are perceived as having brighter bright states and darker dark states by limiting peak voltage levels across the pixels.  A first set of LCD electrodes are continuously driven with signals each comprising a train of pulses that: are periodic in time; have a common period T; are independent of the information to be displayed; and are preferably orthonormal.  A plurality of column signals are generated from the collective information state of the pixels defined by the overlap with a second electrode pattern.  Each column signal is proportional to the sum obtained by considering each pixel in the column and adding the voltage of that pixel's row at time t to the sum if the pixel is to be "off" and subtracting the voltage of that pixel's row at time t from the sum if the pixel is to be "on".  If the row signals only switch between two voltage levels, the sum may be represented as the sum of the exclusive or (XOR) products of the logic level of the amplitude of each row signal times the logic level of the information state of the pixel corresponding to that row.       Hardware implementation comprises an external video source, a controller that receives and formats video data and timing information, a storage means for storing display data, a row signal generator, a column signal generator, and at least one LCD panel.  Alternative embodiments provide gray scale shading and circuits to reduce the magnitude of the column signals, as well as the number of column voltage levels required to generate a displayed image.
